This slide presentation discusses the theory that organic acids will complex with Fe(III),
so they both get sorbed onto granular activated carbon (GAC);
arsenic will adsorb onto the iron in
the organic carboxyl-iron complexes; and,
rusty iron will magnify the arsenic
removal capacity of the organic
carboxyl - iron preloaded GAC. Experimental conditions included:
bituminous coal based activated
carbon (Ultracarb) from U.S. Filter
# WESTATE;
groundwater from Rutland, Massachusetts contained
arsenic concentration ranges from
45-55 ppb; and,
arsenic analysis is conducted via
ICP-MS method. Specific topics covered include: organic carboxyl-iron
complexes for pre-loading GAC; RSSCT of Citric acid-Fe preloaded GAC; RSSCT's with CA-Fe preloaded GAC; digestion of the arsenic adsorbent; arsenic distribution of CA-Fe-pH6 column; arsenic distribution of CA-Fe-pH6
column; conclusions and future research.
